2 Information Pressure measurement engineering Different pressure types Absolute pressure (P abs ) The pressure which applies to the vacuum in the universe (zero pressure) is known as absolute pressure. Absolute pressure has abs as its inde. Measured pressure Relative vacuum Atmospheric pressure difference, positive pressure Atmospheric pressure difference (p e ) is the difference between an absolute pressure (p abs ) and the respective atmospheric pressure (p e = p abs - p amb ). This is generally referred to as positive pressure. Measured pressure Atmospheric pressure Pressure sensitive element Pressure sensitive element Differential pressure, pressure difference ( p) The difference between two pressures p and p 2 is known as pressure difference ( p= p -p 2 ). If the difference between two pressures is a variable, this is referred to as differential pressure (p, 2 ). Measured pressure Measured pressure 2 Atmospheric air pressure (P amb ) This is the most important pressure for life on earth. Atmospheric pressure is created by the weight of the atmosphere surrounding the earth. The atmosphere reaches a height of up to appro. 500 km. Pressure decreases constantly up to this height (absolute pressure P abs = zero). Atmospheric air pressure is also influenced by fluctuations in the weather. The average P amb at sea level is Hectopascal (hpa) or millibar (mbar/ normal pressure in accordance with DIN 343). Typically this value can fluctuate by ±5 % if there are low or high pressure weather areas. Pressure sensitive element Measuring principle When designing pressure meters, the principle of the effect of pressure on a defined area is almost always used. This is then retraced to a measurement of force. The following formula applies: Pressure (p) = Force (F) Area (A) Pressure meters Advantages: Electrical pressure meters There is a displacement of -3 mm in elastic pressure meters. The deformation in electrical pressure sensors is only a few µm. Due to this very low mechanical deformation, electrical pressure meters / sensors have an ecellent dynamic performance and low material stress resulting in high endurance levels and long-term stability. Electrical pressure meters can also be manufactured in very small sizes. measuring meters have an accuracy of ±0.05 % of the full-scale value. In the case of mechanical manometers, such accuracies cannot be read on account of the paralla error and mechanical performance of the springs. Electrical precision meters with LCD display often have a resolution in the thousandth range of Types of pressure meters Liquid pressure meters U-tube manometer Inclined tube manometer Multi-liquid manometer Float manometer Pressure balances with sealing liquid Piston pressure meters Piston pressure meters with springloaded piston Piston pressure scales Electric pressure sensors and pressure meters Sensor principles with strain meters Sensor principles with path measurement Compression meter Ionisation pressure meter Friction meter An additional advantage is the easy-toread display. Considering today s technology standards, accurate pressure measurement is becoming more and more important.

10 testo 34 The complete testing system for gas and water pipes Unique Efficient measurement due to absolute pressure compensation testo 34 independently compensates fluctuations in absolute pressure during volume flow measurement via absolute pressure compensation. Fast Zeroing phase for connected pipe To determine P efficiently and quickly, zeroing to ambient air pressure takes place while the measurement is in progress. This eliminates interruptions and removal of pipes. Efficient Measuring using standard test pressure compensation with feeding unit The flow test which is independent of gas mains, has the advantage that pressure fluctuations in pipes can be compensated.

High speed testo 525 carries out 0/20 measurements per second. Fast measurement is necessary so that pressure drops can be recognised and recorded. In the case of high speed measurements, the user can select when the measurement is to be started. The following can be selected: immediately Measurement starts running ad hoc Overshooting Measurement starts once a specific limit value is overshot Undershooting Measurement starts once a specific limit value is undershot. A trigger mode can also be set up. If a limit value is eceeded, you can determine how long afterwards measurements can continue. Recording stops once the specified time has been reached. If the limit value is again eceeded, recording begins again. This mode is ideal for troubleshooting systems. Additional information at 3

The measurement rate (0.04 seconds, second to 24 hours) and the number of values to be saved are freely selectable. The maimum memory size is 25,000 readings. The readings are saved under separate names for the sites (ma. 99 sites) - with retracing guarantee. Online measurement for large quantities of data can be activated via PC. Inspection of transmitters with 4 to 20 ma interface All transmitters or non-testo probes (in 2 or 4 wire systems, 8 V) can be connected to the 4 to 20 ma interface. Scaling is carried out on the hand-held measuring instrument. Major benefit: The transmitter connected does not need its own power; it is supplied by the testo 52 or testo 526 pressure meter. Documentation on site Easy data management via PC Measurement protocols can be printed on site. No awkward cables required on account of the infrared interface. Long-term legible thermal paper ensures that measurement data documentation can be stored for up to 0 years. The saved measurement data can be easily analysed and processed using the software available. Readings are taken by the instrument and can be depicted online by the software. Pressure drops can be protocolled online in cycles of 0.05 seconds in the Fast Measurement menu. Since, in most cases, pressure drops cannot be predicted, a rule can be defined via the trigger function; the pressure drops are then filtered out and stored separately for the user in indeed pages. 4 Additional information at

18 testo 36-4 testo 36-4 Set the fast and reliable leakage detector for all common refrigerants testo 36-4 Set 2 specially for ammonia. The sensor is permanently monitored and shows malfunctions or contamination in the display. The use of test leaks is thus no longer necessary. If dirty, the sensor can be easily cleaned and is immediately ready for use again. When leaks are detected, the display changes from green to red. An audible signal additionally informs of leakages detected. Using the earplug, the testo 36 can also be used in loud surroundings. The maimum indicator function shows maimum leakages and so facilitates the identification of leakage locations. The fleible gooseneck allows the optimum positioning of the sensor close to the piping or the leakage location. A simple change of sensor by the user turns the 36-4 into an ammonia detector.

The recorded data is analysed in the fastest time on your PC. testo 556 and testo 560 save all the readings quickly and reliably. Electronic refrigeration system analysers can store over 60,000 readings. In this way, largescale measurement series lasting several days can be logged without any problem. Measurement data stored in the analysers is transmitted to your PC using the interface cable. The data is shown in graph or table form. Issuing logs for customers "EasyKool" software manages all customer addresses, systems and individual customer and system information. The data recorded relating to repairs, leak tests or evacuations in refrigeration systems can therefore be easily allocated to customers. The most important data such as customer address, system, refrigerants and date are automatically fed into tables or graphs. Managing refrigerants and downloading new refrigerantsl PC software lists all of the available refrigerants. Additional refrigerants can be downloaded at any time to the analysers using the Testo website and software. Up to 40 refrigerants can be managed on testo 556 and testo 560 at any one time. All or the refrigerants identified in the list by a mouse click can be added. In this way each refrigeration system analyser can be individually equipped with refrigerants. "EasyKool" software can do even more... - Reads out and deletes memory contents of analyzer - Online measurement - Refrigerant management - Import of system data e.g. from Ecel Additional information at 2
